In ver 2.2.0 and previous versions, audacity will crash when I use shift-right arrow to move the cursor while playing.
It only happens when I hold those keys down for quick movement through a large file. Single hits will work normally.
When run from a terminal I get the error:
audacity: src/hostapi/alsa/pa_linux_alsa.c:3641: PaAlsaStreamComponent_BeginPolling: Assertion `ret == self->nfds’ failed.
Aborted (core dumped)
Also, if I change the output stream, I get no audio, but the crash doesn’t happen.
I get the same crash message using Audacity 2.2 on PCLinuxOS but only when recording with software playthrough of input set to on (Preferences, Record Tab). I’ve got separate installations, with and without pulse audio, and the same thing happens in both cases. I found this forum when I put the error message into a Google Search.
On Linux, Software Playthrough is not normally required because PulseAudio can provide that. “Playthrough” should only be enabled in one place, either in Audacity, or in the sound system (usually Pulse). If both are enabled, they will fight for access to the audio hardware, and Audacity will probably lose (crash).
